Sartorius, Q3400--90------N, Quartz Microfiber Filters / Grade Q3400

The grade Q3400 is made of 100 % high-purity quartz microfibers only and pre-heated to guarantee excellent weight and dimensional stability. The filters are especially suitable for emissions monitoring at temperatures of up to 900°C and wherever filters of the highest purity are needed. A trace element analysis is performed for each single lot and its certificate of analysis is available on demand.

Applications Examples:
Analysis of dust levels according to EN 13284 1:2001
Emission monitoring at high temperatures (air pollution)
Analysis of hot and acidic gases
Trace element analyis
Analytical and gravimetrical analyses
Determination of PM10/PM2.5 mass concentration in flue gas – Measurement at low concentrations by use of impactors according to ISO 23210:2009
